The complete genome sequence of the giant Pseudomonas phage Lu11 was determined, comparing 454 and Sanger sequencing. The double-stranded DNA (dsDNA) genome is 280,538 bp long and encodes 391 open reading frames (ORFs) and no tRNAs. The closest relative is Ralstonia phage ϕRSL1, encoding 40 similar proteins. As such, Lu11 can be considered phylogenetically unique within the Myoviridae and indicates the diversity of the giant phages within this family.
